FAQ

Q1: Is this crankshaft a direct replacement for my Mitsubishi S4L1 engine?

Yes, this crankshaft is specifically machined for the S4L1 engine. It is a direct replacement part. However, we strongly recommend verifying your original part number (8-98023-526-0) and measuring the stroke of your old crankshaft (108mm) to confirm fitment before installation.

Q2: What is the recommended installation procedure?

Installation should be performed by a qualified diesel mechanic. Ensure the engine block is clean, replace all main and rod bearings, and torque all bolts to the manufacturer’s specifications. It is critical to check the crankshaft end-play and journal clearances using plastigauge during assembly to ensure proper oil clearance.

Q3: How do I maintain this crankshaft after installation?

Maintenance primarily involves regular oil changes using the correct viscosity oil (as specified for the S4L1 engine) and replacing the oil filter. Clean oil is essential to prevent premature wear on the crankshaft journals and bearings. Avoid engine overloading and overheating to maximize the crankshaft’s lifespan.
